To all whom it may concern:

Be it known that l, SELDEN L. SIMPSON, a

citizen of the United States, residing at Cleveland,- in the county ofCuyahoga and State of Ohio,- have invented certain new and usefulImprovements in Fiber Tires for Vehicle-Wheels; and I' do hereby declarethe following to be a full, clear, and exact de- .scription of-theinvention,such aswill en able` others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the letters of reference marked thereon,which form a part of this specification.

This invention relates to new and useful' improvements in ber tires for.vehicle wheels and the purpose of theinvention is to produce a compacttire of ber, tlie outer ends of which are presented as a tread surface,the ber being .reduced to a compact form by hydraulic pressure and heldby clamping plates designedto be detachably held to a metallic tirevupon the rim of a wheel.

The invention comprises Vfurther'a ber tire for wheels having concentricrows of stitching, the ber being conned by clamp- V ing plates securedto a metallic tire upon the rim of the wheel, the plates being adaptedto 'be cut away adjacent to therows of stitching to compensate for'wearupon the tread surfaceof .the tire. v

. v- The invention comprises'various other details of construction andcombinations-and arrangements of parts which will b e hereinafter fullydescribed and then specificallyv de ned in the appended claims.

. I Aillustrate my invention in the accompa- "nying drawings, inwhichz-Figure 1 is an elevation showing a portion' of one of saidclamping plates cut away. Fig. 2 is an enlarged detail perspectiveviewof aportion of the tire, parts being cut away tobet-ter illustratefeatures of the invention. Fig. 3

is a transverse sectional View through the tire and rim of a wheel. Fig.4 is an'enlarged detail view of' a section ofananchor` age plate, andFig. 5 is a detail section of a mod ied-means of holding the ber in acompact form. Y

Reference nowbeing -had to thedetails of the drawings by letter, Adesignates an ordinary rim of the ,vehicle wheel having v the usualmetallic tire B thereonl andl about thecircumference of'which it is my.purpose to other substance which will have being -held in clamping rel-ing the wheel -1nes centric rows of- Aa section of thekring.

SPECIALTY apply the aber are c ywhich is' made up er I any form of sisalhemp with the strands of theber radially disposed oron end so that.their outer ends will form the tread surface thereof. The ber, prior toits being reduced to form for use, is preferably treated'with anysuitable material, such as creosote, 'tarL or any a tendency to preservethe ber and marke the same walmaterial, such as Mani-la or ter proof,after whichA the mass of ber is subjected to hydraulic pressure toreduce lit to a compact form. Rows of stitching l) are formed inconcentric series through the tire after having been reduced to acompact form, which stitching able material, such as wire, wax threadsor may be of any suitother material, the purpose of the stitching" beingto hold the,outer ends of theber adjacent to the tread surface, in acompact form and which willzhave al tendency to. vent spreading. of theber as would lidlybe the case without the stitching. After the tire hasbeen compressed hydraulica'lly-and stitched, the retaining-rings E,preferably of metal, are laced one against each opposite side of thetire with the inner edge of said rings -restin uponV the circumferenceof the tire B, said ation against-the opposite sides of the tire bymeans of the rivets F. In order to'hold the ringsin se` cure clamping.relation withv .the '-tire, hy-

rings' or plates E draulic pressure is applied to* the outer faces 'ithereof 'fwhile Athe rivets F are inserted through after the ends Aofthe rivets are upset vfor clamped, saidp'lates will serve vto hold thetire securely in a compaetorrn Said rin are scored at locationsdesignated by letters F and F- outer circumferences the rings or platesand the tire and,

at suitable loca-tions from their to indicate sections' Awhich areadapted torba' t away by placmxa lathe nd snbJectingithe `rings tocutting `tools for the purpose of reg,

.ducmgthe diameters 5f the rings tocomensate for the wear of the tire.Saidfscore F-and E ,z. are spaced apart distances about equal to 'tedistance between the con-- stitching so that', when the outercircumference ofthe brous tire is..

worn away toalocation adjacent .tol the outer eircuinferences oftherings, theflife of thetiremay beg'prolo ed by cuttingI away nVhensections of the tire are worn away, it will be observed that the nextinner row of stitching will serve to hold the outer ends of the fiber ina compact form and from spreading until other sections of the rings arecut away to further compensate for wear. Said compression rings E areprovided at intervals with registering apertures 'adapted to receivethebolts G which are passed through the liber tire and also throughgrooves in the anchorage rin Hyand nuts G are fitted to the threade endsof the bolts G. `It will be noted that the heads of the bolts G areadapted to bear against one edge of the tire B while the retaining nutsG upon the other ends of the bolts bear lrictionally against theopposite edge of the tire B and serve as means to securely hold thefiber-tire in place about the rim of the wheel. Said anchorage ring Hpasses about and engages the circumference of the tire B at any suitablelocation, preferably midway its width, and has its outer marginal edgecut to forni a series of wings or lugs which are curved laterally indifferent directions and adapted to engage the fiber and 'serve as asecure means for anchoring the inner portion of the fibrous -tire inplace. Said anchorage ring is adapted especially for use Where tires ofunusual width are used and adapted to sustain greater loads upon whichtires heavy strain would come.

From the foregoing, it will be noted that, by the piovision of a tiremade as shown and described, as the tread surface of the fiber becomesworn, uniform sections of the rings may be cut away to compensate forthe wear, the stitching serving to hold the outer tread surface of thetire adjacent to the marginal edges of lthe rims and, where thegreateststrains come upon the fiber, in a compact form and preventingthe fiber from spreading.

In Fig. 5 of the drawings, I have shown a slight modification of astapling means for holding the fiber in a compact form and which may beutilized in' placeA of the stitcliing, if desired, and in which figurethe staples, designated by letter T, are independent one of another.

From the construction shown, it will be noted that the fibrous tire maybe easily and quicklyu'einoved from the rim ofthe wheel' when desiredfor any purpose by simply removing the nuts fro-m the bolts G, allowingthe fibrous tire and the anchorage plate to be removed together with thebolts, as will be readily understood.

What I claim to be new is 1. A vehicle tire made upof fiber, the outerends of which form a tread surface, reducedV to a compact form andhaving concentric rows vof stitching therein, clamping rings embracingthe opposite sides of the tire and concentrically scored,means forfastening said rings to the fibrous tire, a rim, a metallic tire aboutthe circumference thereof, an anchorage-ring about said .metallic tire,the outer marginal edge of said anchoring ring having adjacent portionsat the reduced to a compact form and having con- A,

centric rows of stitching therein/a rim, a

metallic tire about the latter,A clamping'- rin'gs, concentricallyscored to correspond to the rows of stitching of the fibrous tire, thescores being arallel -with the concentric rows of stitching, the innermarginal edges of the rings enga ing' the circumference' of saidmetallic tire, olts passing through said rings and fibrous tire, theheads of the bolts engaging one of the marginal edges of the metallictire, and nuts upon the threaded ends of the bolts engaging the otheredge 'of' thelatter.

In testimony whereof I hereunto affix" my signature in the presence of.two witnesses.
